TRANSOM OPERATOR.

APPLICATION FILED lU LY 12. I911. Patented Oct. 1, 2 SHEETS-SHET 2- X J V I I W /6 Figs. 2 and 4 of the drawings. A bar or buffer 27 is formed upon the inner end of the plunger 23 and it has a pair of contractile springs 28 connected thereto which are seated in recesses 29 formed'i'n the bearing members 19 and 20 and they havetheir'in nermost ends connected to the bearing members for moving the buffer 27 inwardly toward the casing 16 and for forcing the button or head 24 outwardly.

' When the button 24 is moved inwardly within the casing 16, the meshing engagement between the pinion 17 and the rack teeth 15 will move the bar 14 vertically, which" will, through the meshing engagement of the rack teeth 13 with the pinion 12 rotate the'shaft 10 and consequently r0- tate the crank mechanism composed of the arm 9 and rod 8 aboutthe'axis of the shaft 10 for swinging the transom 2 upon its pivot 3 into an open position, and when the plunger 23 and. head 24 are forced outwardly by the actionof the springs 28, the bar 14 will be moved inan opposite direction which will-rotate the shaftv 10 in an opposite direction and swing the transom upon its pivot 3 to a closed position. 7 Y

e A look structure is provided forholding the transom in' adjusted pivotal position, and this lock structure includes a locking pin 30 which is slidably carried by-a-suitable support ,31 which is formed uponthe I plunger 23. The support 31 is substantially U-shaped and thepin 30 has-a collar 32 formed thereupon which engages the inner surface" of the'outer leg or side 33 of-the U-shaped' supporting bracket 31 for limitingthe outward movement of thelocking 55. mounted a pin 41. :Thepin 41 hasa head pin 30. A spring 34 is coiled about the locking pin 30 and ittends'to force this pin outwardly into one ofthe spaced openings .35 formed in the-keeper 36 so-that when the pin 30 isseated in onset the spaced openings 35, the plunger 23 will be held against movement which will in turn hold the transom 2 against ment.

The locking pin 30 has a shank 37 formed pivotal m ovethereupon which is slidably'seated in the plunger 23. "The shank 37 has-an opening 38 extending-transversely therethrough, one

side of which is inclined throughout a portion of its distance as shown at 39 in'Fig.

2 of the drawings. The plunger 23 is provided with a bore 40 in which is slidablv 3 42 formed upon its outer end which'pro- -jects through the' closing plate 26- iof the cap 24.;FA spring 43 is *coiledaboutthe pin 41,:and. has one end connected': to the a [pin and the-other end to: the plate -26 so .that the action of-the spring wil1=hold the pin 41 outwardly except when'fit -iszforo'ed inwardly by 'manual pressure. The inner pin out of the opening 35, so as to permit the plunger 23 to be moved eitherinwardly' for opening .thetransom or outwardly for closing the transom.

In the operation of the improved transom operator, 'thepin 41 is first forced inwardly whichreleases the catch structure and moves the head 42 into engagementwith the outer surface of the plate26 so that further in ward movement will move the plunger 23 inwardly and rotate the shaft 18 through themeshing engagement betweenrthe teeth 22 formed upon the plunger and the pinion 21 which is carried by theshaft '18.; The

rotation of the shaft 18,will be administered to the shaft 10 through the medium of the pinions 17 and 12 and the bar 14 as previously described. H 1

E From, the foregoing description taken in connection withv the accompanying draw- 1 ings the advantages of construction and of the method; of operation of the improved transom operator will be readily apparent to those skilled inthe art to which thisinvention appertains and, while in the foregoing description the principle of, the operation of this invention has been described together with various: features of, construction, it is to be understood that certainuminor fea-'- tures of construction, combination and arrangement-of parts maybe altered 'to ,suit

practical conditionsqprovided SllOl'lsilltBIil- V trons} are comprehended within of what is claimed. H w
